I don't understand why they wouldn't give a pre-release patch to the bug reporter (especially if it's someone like Google) for them to analyse before doing a final release.
If they were actively working with Project Zero instead of being seemingly silent, this wouldn't happen
This is where FOSS is still winning and will always win. Fixed happen in the open and bad fixes can be called out
I’m not sure why you think it’s the researchers responsibility to verify patches. It would be nice, especially if they’re knowledgeable in the code, but Microsoft have the resources to put someone else in that position too.
The researchers in this case literally checked the patch after release. It costs nothing to send them a pre-release and ask the question
That’s different. I’m not here to mark your work but if you publish your work, I’m happy to publicly point out that you’re wrong, especially if you’re Microsoft size and should have work checkers internally and are continually doing the wrong think and putting people at risk as a result.
